EVOMS Boost Recirculation Valve Set 2.0 (997.1 Turbo)


Designed to fit:

  • 2006 - 2009 Porsche 911 Turbo / Turbo S / GT2

Product Details

Evolution MotorSports has engineered a performance spring and cap upgrade for the 997TT. The EVOMS 997TT Boost Recirculation Valve set is a direct replacement for the OEM units and features an improved and more efficient design. Their BRV is CNC machined from aircraft grade 6061-T6 aluminum, and hard anodized. Their CAD designed BRV employs the same operating principal from the factory unit, but with larger pre-load on the spring, and a billet cap to replace the factory plastic unit known for failures. Combining our successful design principles, stringent theoretical computer and real world testing, the EVOMS 997TT BRV eliminates issues of boost leaks, diaphragm sticking, and deterioration that is consistent with the OEM valve in higher than stock horsepower applications.


  • Direct replacement for the OEM unit
  • Features an improved and more efficient design
  • CNC machined from aircraft grade 6061-T6 aluminum, and hard anodized
